Because most of the watches are showing 10:10 is?

You’ll probably have noticed that most of the watches in the ads or on the shelves show 10:10…
There are several explanations for the phenomenon that has become a constant in the marketing watch.
The most prevalent is that it seems like the logo of the construction company without being blocked by the indicators, while at the same time the position of the indicators suggests a smile.
Another version is that the indicators work like a frame for the logo of the brand and steer the gaze on it.
The most curious explanation is that the indicators show the time that he was shot Abraham Lincoln (president of USA), which although more mysterious does not seem quite possible.
